I previously reported on my satisfaction with the OWC KX case for iPhone, which I now rely on every day because it works (protection and much better for hand grip).
The new KX Mini case for the Apple iPad is the same idea, adding protection against drops and bumps, though I suppose a direct hit on the front glass on a sharp edge would be Bad. Watch this video of an iPad Mini tumbling down hard stairs .
The metal shell of the Apple iPhone and iPad is elegant to the eye but not so easy to hold onto without inadvertant drops. So I especially like having this kind of case on my iPhone when cycling, but even the iPad is prone to slipping off a lap or similar.
